And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force - and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy. Now, from her solitary life as a Ranger keeping order across the galaxy, Lanoree has been summoned by the Je’daii Council on a matter of utmost urgency.

As ruthless apprentice to Darth Vader, Starkiller was mercilessly schooled in the ways of the dark side, commanded to exterminate the last of the purged Jedi Order, and groomed for the ultimate Sith power play: Assassination of the Emperor.
